[c-nsp] Searching for cheap IPv6 NAT-PT Cisco-device

[Jeff Wojciechowski]

Pitor-

Please forgive my ignorance:

I am attempting to get familiar with this myself on a 2811 running 12.4(24)T4 - but that's IP Base.

I don't even have the option to assign an IPv6 address to an interface.

Do you happen to know which flavor image I need?

Regards,

-Jeff Wojciechowski

Hello Andreas,

In general performance of NAT64 is not really high. I remember on Cisco
2801 ~4Mbit was all I could get. I used one of the latest 12.4T release, 12.4(24)T as far as I remember. The smaller reasonable device to play with would be Cisco 1841 but it's also available on 870 and 880 platform. Of course for the production network I'd check how much traffic it's going to handle (and not only in number of TCP sessions that have to be translated but throughput itself, because NAT64 is process switched since 12.4(20)T, until that it was fast switched).

Regards,
